solution

You want to find which expression will give a better estimate for

138

Look at

140

140 is close to 138, and 20 is close to 22. 140 can be easily divided by 20. So,

140

is a good way to estimate

138

Look at

130

130 is also close to 138, and 30 is also close to 22. However,

130

cannot be easily divided. These numbers do not make estimating

138

easy.

So,

140

is a better way to estimate.

Now, use

140

to estimate the quotient.

Use basic division facts and division patterns to help you.
